A lot of people think that because it is an "electronic" ignition, the Pertronix sends 12V positive to the coil - but that is incorrect. All the Pertronix does is electronically replicate what your points did, which is (temporarily) connect the coil to ground. Hence the coil should be used with whatever resistor it had originally. The coil resistor has (essentially) nothing to do with the Pertronix device itself.

I'm trying to sort out some engine/automatic transmission issues and cannot find answers in my web/forum searches. The engine is a recently overhauled 289 which had a R1 camshaft and new valve springs installed. The engine was also bored .060 . The prior owner had the work done. So I have some questions. Life and engine performance require tradeoffs:

1. Will the camshaft require a higher idle speed over the stock 550 RPM? Idle seems rough at that RPM. Yes, the R1 increased

looking to see what it would take to replace a broken flathead 6 & 3spd from a 58 scotsman 4 door and install a small block chevy or BB & 5spd, besides having to install motor and trany mounts. Any takers? with out a frame change. Anyone got pics of this.
